I have modified a number of wordpress plugins to help with my domaining needs. Some simple container widgets for example I have a skyscraper aff code widget holder, where I input my aff code (say Awin/Amazon Widget) and drop the widget on my side bar. I've adjusted it to various sizes for my own ordering. I've also created a fixed Amazon one, which you just put your aff code in, I have various others that just make filling my side bars easier. I was wondering what you have created ?
